Across the Nation
As we review the state of the nation's snow and water reserves, we are witnessing a complex interplay between snowfall, streamflow, avalanche risks, and reservoir levels that have immediate implications on outdoor activities, water management, and community safety.
Snowfall and forecasts show a mixture of weather patterns across the nation. The Sierra Nevada range in California is experiencing significant snowfall, with the Mount Shasta Avalanche Center issuing a 'high' danger warning, urging extreme caution due to very dangerous avalanche conditions. In contrast, Colorado's Avalanche Information Center reports 'moderate' conditions, suggesting heightened caution on specific terrain features. Meanwhile, regions such as Southern Oregon are under 'no rating' for avalanche danger, indicating relatively stable conditions.
Reservoir levels present a mixed picture. For instance, Lake Winnipesaukee in New Hampshire currently sits below its average gauge height, whereas the Indian Lake in New York is closer to its average. In general, most reservoirs are maintaining levels near their average, but notable deviations like Maurice R at Union Lake Dam in New Jersey reflect significant decreases in streamflow, indicative of potential water supply concerns. As for the West, despite heavy snowfall, reservoirs like Dillon and Granby in Colorado are reporting storage below average levels, continuing the trend of concern for water availability in these regions.
The combination of these factors impacts various sectors significantly. For example, cities like Los Angeles are bracing for potential flooding due to heavy rains, while areas with recent burns are under watch for mudslides. On the flip side, regions receiving fresh snowfall are attracting skiers and snowboarders, yet they must stay vigilant about avalanche warnings. Additionally, river rafting enthusiasts eye streamflow levels to gauge the potential for their sport in areas like the Mississippi River, which is showing high streamflow levels at several points. As spring approaches, the intersection of melting snowpack and rainfall will be critical to monitor for flood risks and water resource management. Read more
